What i am trying to achieve is have one input form populate another.

$(document).ready(function(){

      $("#cr").change(function(){

            $("#LDL").val($(this).val());

      });

});

This code works great. If i put "1" in the text field and click out it will populate the LDL field with 1, 

What i would like is to enter number "1" in the CR text field and output "CR=1/".

Is there any way of making it Static?

Here is the Fiddle!
